Overview

For Mausingfield owners looking to set up a rifle for a different chambering, this bolt head and extractor kit provides the parts needed to support caliber changes on compatible 2019-or-later rifles. It is intended for use with the ARC Mausingfield action, where barrel swaps can be done without a gunsmith fitting the barrel. The included bolt head is machined from hardened steel and finished with a DLC coating. This is a practical component for shooters who want a more flexible rifle setup, while staying within the compatibility limits of the platform.

Considerations & Trade-offs

  • This kit is only for Mausingfield rifles developed in 2019 or later, so compatibility needs to be confirmed before purchase.
  • It is a caliber-change component, not a complete rifle part set, so it is intended for owners already set up with the Mausingfield platform.
  • The product is specific to a 0.378" right-hand bolt head and extractor configuration, so it will not suit other bolt-head setups.
  • Barrel changes are described as easy on the Mausingfield action, but the kit still serves a platform-specific role rather than making the rifle universally convertible.
